Description

TECHNICAL FIELD

[0001] The utility model relates to lubricating oil detection technical field especially a sampling equipment for lubricating oil detection. BACKGROUND

[0002] Lubricating oil is a kind of liquid for lubricating and reducing friction. It is coated between machine parts or injected into moving parts such as bearings, gears, etc. to reduce the friction between two surfaces, prolong the service life of equipment and improve work efficiency. The transportation of lubricating oil is usually completed by oil storage barrels. After batches of oil storage barrels arrive at the destination, the detection personnel need to sample the lubricating oil in the oil storage barrels and detect the sampled lubricating oil by moisture detection equipment to detect whether the quality of lubricating oil meets the standard. The traditional sampling equipment still has some deficiencies in use: first, in order to detect the accuracy of the value, the lubricating oil at different depths of the same barrel needs to be extracted in batches. However, the manual operation is not easy to control the depth, and the sampling tool needs to be stationary for a period of time after being inserted into the oil storage barrel. It is time-consuming and laborious to hold the sampling tool by hand. Second, the time-consuming sampling work is not conducive to the preservation of lubricating oil, which is easy to contaminate the lubricating oil. Third, when the sampling tool is taken out of the oil storage barrel, the lubricating oil is easy to adhere to the outer wall, which not only pollutes the ground and causes unnecessary waste, but also is time-consuming and laborious to clean up. If the lubricating oil is not cleaned up in time, it will contaminate the lubricating oil in the oil storage barrel when the sampling tool is inserted into the oil storage barrel again. SUMMARY

Several elastic cards 4 are evenly spaced along the circumference of the top of the support sleeve 1. A locking element 5, matching the support sleeve 1, is provided on the support sleeve 1 above the support handles 3. A sampling tube 6 is vertically arranged inside the support sleeve 1. An annular rubber band abuts against the outer wall of the sampling tube 6 along the circumference of the lower part of the inner wall of the support sleeve 1. The film 7 has an oil passage hole 8 on the bottom plate of the sampling tube 6. A connecting rod 9 is vertically installed inside the sampling tube 6. The upper end of the connecting rod 9 moves upward and passes through the top plate of the sampling tube 6 to connect with the pressing handle 10. The lower end moves downward and passes through the oil passage hole 8 on the bottom plate of the sampling tube 6 to connect with the sealing block 11. A return spring 12 is installed on the connecting rod 9 between the top plate of the sampling tube 6 and the pressing handle 10. A gripping handle 13 is installed on the outer wall of the sampling tube 6 on the side corresponding to the pressing handle 10. A rubber piston block 14 is installed on the connecting rod 9 to abut against the inner wall of the sampling tube 6.

[0022] Optionally, a sealing seat 17 is arranged on the bottom plate of the sampling tube 6, and a funnel-shaped extrusion groove 18 is arranged at the bottom of the sealing seat 17 and communicates with the oil passing hole 8. The sealing block 11 is spindle-shaped, and the inclined part at the upper part of the sealing block 11 abuts against the inner wall of the extrusion groove 18 of the sealing seat 17. The sealing seat 17 plays a role of guiding the lubricating oil adhered to the outer wall of the support sleeve 1 to flow through the spindle-shaped sealing block 11, quickly gather and drop downward, so that the adhering amount of the lubricating oil is convenient for people to clean.

[0023] The device is used, need first open the cover on the oil outlet of the oil storage tank, then connect the threaded slot 2 of the support sleeve 1 on the oil outlet of the oil storage tank, by turning the support handle 3, so as to realize the radial rotation of the support sleeve 1, and make the threaded slot 2 connected on the oil outlet of the oil storage tank. Then, the sampling tube 6 is inserted into the support sleeve 1 from bottom to top, and the corresponding scale line 15 on the support sleeve 1 is selected according to the required sampling depth of the oil storage tank. After the position is selected, the position of the sampling tube 6 is fixed by the locking member, and the locking sleeve 501 is rotated radially by rotating the adjusting handle 502, so as to make the threaded connection on the top of the support sleeve 1, and the design of the upper part of the locking sleeve 501 inwardly converging in the process of moving downward can drive the elastic clamping plate 4 to continuously inwardly converge and clamp the sampling tube 6. When sampling, the lower pressing handle 10 is pressed by hand, which makes the lower pressing handle 10 gradually approach the gripping handle 13, and the connecting rod 9 pushes the rubber piston block 14 downward, until the rubber piston block 14 moves to the bottom plate of the support sleeve 1, at this time, the sealing block 11 is separated from the sealing clamping seat 17.
